| // gmock expectations for the response to a method. Every method |
| // returns the object itself for chaining. |

| // Usage: |
| // // Setup |
| // MockObjectWriter mock; |
| // ExpectingObjectWriter ow(&mock); |
| // |
| // // Set expectation |
| // ow.StartObject("") |
| // ->RenderString("key", "value") |
| // ->EndObject(); |
| // |
| // // Actual testing |
| // mock.StartObject(StringPiece()) |
| // ->RenderString("key", "value") |
| // ->EndObject(); |
